MOP.

Specification of Letters Patent.

Patented Sept. 5, 1916.

To all whom t may concern:

Be it known that I, EDWARD H. TATE, a citizen of the United States,residing at Malden, in the county of Middlesex and State ofMassachusetts, have invented new and useful Improvements in Mops, ofwhich the following is a specification.

This invention relates to a mop having a substantially triangular frameor head to which a handle is connected and mop filaments of fibrousmaterial depending from said head, the mop being usually operated in adry condition or treated with a dust arresting composition.

The invention is embodied in the hereinafter described improvementsrelating to the construction .of the frame, the means for connecting thehandle therewith, said means permitting the handle to occupy variousangular positions relatively to the plane of the head or frame, to a mopelement of improved structure cooperating with'the head or'frame, and tomeans for securing the mop element to the head or frame.

0f the accompanying drawing, forming a part of this specification:Figure 1 represents a top plan view of a mop embodying my invention;Fig. 2 represents a section on line 2-2 of Fig. 1; Fig. 3 represents aperspective view of the crossbar and handle socket shown by Figs. 1 and2; Fig. 4 represents a section on line 1-4 of Fig. 1; Fig. 5 representsa fragmentary sectional view showing a part of the neck portion of themop element; Fig. 6 represents a fragmentary perspective view showing aportion of the mop element as it appears prior to its engagement withthe clamp hereinafter referred to; Fig. 7 represents a fragmentaryperspective view showing portions of the mop element and a portion oftheclamp; Fig. 8 represents a fragmentary side view showing theJ endportions of the clamp and the coupling member connecting said portions;Fig. 9 represents a section on line 9-9 of Fig. 8; Fig. 10 represents aside view on a reduced scale of a complete mop embodyn ing theinvention, a part of the handle being broken away.

The same reference characters indicate the same or similar parts in allthe views.

In the drawings, 12 represents an approximately triangular frame, theouter side of which is grooved, as shown by Fig. 2. Said frame ispreferably composed of a sheet metal strip of concavo-convex form incross section, the ends of said strip being overlapped and united at 13(Fig. 1) by welding, brazing, or otherwise.

To two of the sides of the frame 12 are pivoted a crossbar having ahandle-engaging socket. Said crossbar is preferably composed of a baseportion 14 and ak wing portion 15 integral with the base portion, thecrossbar being preferably formed by bending a sheet metal blank into theangular form represented by Figs. 1, 2 and 3. The crossbar is providedat its ends with ears 16, preferably integral with the base portion,said ears being perforated to receive hinge pintles or rivets 17 whichestablish a hinge connection between the crossbar and the frame 12. Thesaid pintles are preferably engaged, as indicated by Figs. 1 and 4, withbosses 18 formed on two of the frame sides, said bosses presenting fiatsides or faces which are parallel with each other and with the ears 16.

The handle socket is preferably a substantially semi-cylindrical sheetmetal member 20 having ears 21 which are riveted or otherwise securelyconnected with the wing portion 15 of the crossbar, said member 20 andwing portion 15 forming a socket which is semi-circular at one side andiiat at the opposite side, as clearly shown by Figs. 1 and 3. The member2O is preferably embossed at its semi-circular portion to form segmentalor interrupted screw-thread portions 22, adapted to engage acorresponding thread formed on the inner end of an elongated Woodenhandle 23. The crossbar constitutes a strut which prevents the inwardbending of the sides o-f the frame to which it is pivoted. The angularJform of the crossbar when made of sheet metal as shown and describedadds materially to the effectiveness of the crossbar as the strut.

It will be seen by reference to Fig. 2 that the axis of the handlesocket is substantially equidistant from the upper and lower edges ofthe fra-me and that the socket is located mainly within the frame. Thisarrangement enables the handle to assume the dotted line position shownat the right of Fig. 10, so that the mop may be introduced into arelatively low space, such as the space between the floor and a radiatorabove the floor. The handle is also adapted to stand at right angleswith the plane of the frame to enable the mop to be used on a ceiling,and to stand at various intermediate angles.

My improved mop element as here shown is composed of two facing strips24 of textile fabric and a body of fibrous strands 25 usually of twistedcotton yarn laid crossvwise between the facingV strips and projectingfrom the opposite longitudinal edges thereof to form loose brushfilaments depending from the frame, as indicated by Fig. 10. |The facingstrips 24; andthe intermediate portions of the fibrous strands conwiderthan the outer wing to enable it to feo conform to the frame 12.

28 represents a triangular clamping strip, which is preferably afiat-sided strip of steel or other suitable metal, the ends 29 of whichare spaced apart, as shown by Fig. 8. Said grooved outer side of' theclamping strip is formed to hold the inner wing of the mop element `neckagainst the grooved outer side of the frame 12. The

.wings of the neck are united by a longitudinal row of stitches 30,preferably formed after the clampingV strip 28 is interposed betweensaid Wings. rlhe ends of the clamping strip 28 are connected by acoupling member 31, which is preferably a metal bar havthe abruptly bentportion of the mop ele- Yce'A ment neck where the stitches 26 arelocated projects above the upper edge of the frame 12 and constitutes acushion guarding said upper edge and preventing it from strikingwoodwork when the mop is being used. It will also be seen that the outerwing of the Y mop element neck covers the clamping strip V28 andcoupling member 31 and prevents these parts from striking the woodwork.

1 Having described my invention, I claim: 1. A mop comprising atriangular open frame, a crossbar pivoted at `its ends to two of thesides of said frame and having a .Y handle socket located mainly withinthe frame, said crossbar constituting va strut preventing inward bendingofthe sides to which it is pivoted, and a mop element including a neckportion surrounding and clamped upon said frame, and filaments dependingloosely from said neck and from the frame.

2. A mop comprising a triangular open frame, a crossbar pivoted at itsends to two of the sides of said frame and having a handle socketlocated mainly within the frame, said crossbar constituting a strutpreventing f inward bending of the Jsides to which it is pivoted, and amop element including a neck lportion surrounding and clamped upon saidframe, and filaments depending loosely from said neck and from theframe, said neck projecting above the upper edge of the frame andforming a triangular cushion guarding the frame.
